Final answer:
The US Government's attempt to Americanize Native Americans was through assimilation, particularly by dividing reservation lands into small family-sized allotments and enforcing boarding school attendance for Native children.
Step-by-step explanation:
The attempt made by the US Government to Americanize the Native Americans was through assimilation. This policy, largely implemented via the Dawes Act of 1887, mandated an end to communal property and divided reservation lands into individual plots, or allotments, to be owned by Native American families. The goal of these allotments, which were often small family-sized plots of land, was to encourage farming practices among Native Americans, similar to those of European Americans. The Dawes Act also aimed to assimilate Native Americans into a Euro-American way of life by eradicating communal living and tribal sovereignty. The boarding schools, part of Americanization efforts, further forced Native children to adopt English and individualistic cultural norms by separating them from their families and cultures.
